I have an unusual situation, I am a property manager for eleven vacation homes. I do a lot of business with them. After I had talked to them a bit, I met them at their office. I rent high-end vacation homes to clients, and they need everything to work perfectly. Pool Covers, Inc tailored a program to meet my needs, for a very reasonable rate and giving priority to my needs. I advise potential customers to follow through with the maintenance suggested by Pool Covers, Inc. The pool cover mechanism is very complex and is exposed to the elements. They can not be expected to function with out maintenance. So when they suggest maintenance, please get it.
